Abstract: Based on the basic concept of water-consumption-factor in oilfield development, water-consumption-index was defined as water-consumption-factor with injection-production-ratio of 1.Combined with water displacement curve given by Tong Xianzhang, the relationship between water-consumption-index and recovery percent was derived by which the theoretical chart of water-consumption-index was developed.It can be used to evaluate water flood performance and predict recovery factor.The chart is simple and easily understood, which performed well in Shuanghe oilfield.

Key words: Water injection, Chart, Evaluation, Recovery factor, Shuanghe oilfield
